Auckland's food scraps program reduces waste, generates energy, but faces cultural adoption challenges.

Auckland's food scraps collection program, which transports waste to the Ecogas facility for anaerobic digestion, is reducing landfill waste and emissions while generating renewable energy and fertilizer. Participants report less smell and pests, and larger households can request a second free bin. However, adoption among Pacific communities is slow due to communication and cultural barriers. The process also soon aims to enhance glasshouse tomato growth with CO2.
